Embodiment 1

[0053] For patients with sequelae of cerebral hemorrhage:

[0054] S1: The patient has poor muscle strength and mobility, and is assessed to be at high risk of falling;

[0055] S2: collect the patient's height, weight, chest circumference, waist circumference and other data, and input and store them in the database 2;

[0056] S3: Install multiple infrared cameras 31 at fixed positions in the patient's ward for continuous monitoring, set reference infrared light sources 32 around the bed, use infrared imaging technology to obtain patient body contour information, and input the program;

[0057] S4: Process multiple sets of two-dimensional images to reconstruct the three-dimensional contour information of the human body;

[0058] S5: Using human body contour recognition technology to calculate the patient's body position information;

[0059] S6: Calculate the patient's center of gravity and different weight distribution maps according to the actual measurement data of the p...

Embodiment 2

[0063] For the elderly:

[0064] S1: Elderly, with limited mobility, assessed to be at high risk of falling;

[0065] S2: measure the height, weight, chest circumference, waist circumference and other data of the elderly, and input and store them in the database 2;

[0066] S3: Install multiple infrared cameras 31 at fixed positions in the ward for the elderly for continuous monitoring, set reference infrared light sources 32 around the bed, use infrared imaging technology to obtain body contour information of the elderly, and input it into the program;

Embodiment 3

[0073] For malnourished people:

[0074] S1: Malnutrition, limited mobility, a history of falls half a year ago, and a high risk of falls;

[0075] S2: Measure the height, weight, chest circumference, waist circumference and other data of the malnourished person, and input and store them in the database 2;

[0076] S3: Install multiple infrared cameras 31 at fixed positions in the malnourished ward for continuous monitoring, and set reference infrared light sources 32 around the bed, use infrared imaging technology to obtain body contour information of malnourished patients, and input it into the program;

[0077] S4: Process multiple sets of two-dimensional images to reconstruct the three-dimensional contour information of the human body;

[0078] S5: Use human body contour recognition technology to calculate body position information of malnourished patients;

[0079] S6: Calculate the center of gravity and different weight distribution maps of the malnourished person acco...

Abstract

The invention discloses a tumble early warning implementation method, which comprises the following steps of: step 1, acquiring human body contour and position information of a user by using a monitoring system, and identifying the identity of a user; step 2, enabling a data processing system to calculate the gravity center position of the user according to monitoring information in the step 1 andform different weight distribution diagrams; step 3, enabling an identification system to carry out user human body action recognition according to the data information obtained and calculated in thestep 1; and step 4, enabling an alarm system to acquire an identification signal sent by the identification system and send an alarm signal to a doctor-patient terminal. The invention is caharacterized that an infrared camera and a reference infrared light source are adopted so that no damage is caused to a user; the influence of user compliance is small; user behaviors are obtained more visuallyand vividly through reconstruction of a three-dimensional image; the identification system intelligently analyzes and recognizes the user behaviors, and alarm sensitivity and specificity are improvedand an application range is wide.

Description

technical field [0001] The invention relates to a medical management system, in particular to a fall warning realization method and system. Background technique [0002] A fall is when any part of the body accidentally touches the ground due to loss of balance. Hospitalized patients are prone to falls due to physical weakness, disease, unfamiliar environment and other reasons, especially for hospitalized elderly patients, whose incidence of falls is relatively high. At present, China's population has entered the elderly type, and the aging trend of the elderly population is becoming increasingly obvious. The guidance of national policies promotes the rapid development of elderly care institutions. For nursing staff, they will face a larger service population in the future. According to statistics, the annual incidence of falls among the elderly in my country is about 18%, and 60% to 75% of falls will cause injuries. Studies have shown that 80% of hospitalized patients fall...
